Don't look too deep into this, maybe I simply remember wrong
I remember him saying something of a sort but this quote comes from an old BSN thread 
Yeah, I found the same quote earlier as well, and it was so precise I thought maybe he really says that depending on what you do
I'll still keep an eye out when replaying the Leviathan DLC with different squad mates even though chances are slim 
Sooo, today it was time to go to Thessia! This is a bit long, haha.
Well colour me surprised. Or not. The asari Councillor revealed to me that there's an artifact in a temple on the asari homeworld, Thessia. One that might help with the Reapers, that might help identify the Catalyst. I was starting to get p*ssed. I asked why they suddenly thought of helping us. The answer was as I expected. Now that their homeworld burned, they needed my help, so typical. If they would've come forward with this kind of information... They knew we were missing the Catalyst all along! I just can't believe them... but what does it matter now, we need this artifact. Let's see where it gets us.
As we approached Thessia with the Normandy, Joker told me that Thessia was heavily attacked by Reaper forces. Liara was close by and insisted on coming with, I understood perfectly, but I hope she keeps her focus. I told her and James to get ready and grab their gear, and Cortez soon took us down there in the shuttle. Liara was worried, but we talked a bit about the temple and how Benezia took Liara there once. James mirrored my thoughts once again when he told Liara that even killing her own mother did not stop her and that she needs to block out what's happening on Thessia.
But when we arrived, it looked like Earth and Palaven all over again, so I guess it's not gonna be easy for Liara.
We pushed on through Reaper forces several times, taking any support from the asari we could get to make it to our destination. The temple was heavily guarded, but we chased the remaining Reaper forces off.
We started to investigate the temple, looking at various artifacts, and then soon finding the scientists that were supposed to meet us there. Dead. Throats cut. No Reapers, then.
I stood in front of the huge statue of Athame when something happened. I just knew there was a Prothean beacon here. And with this we found the artifacts that were connected to the statue, the last one we activated sent it crumbling, revealing the beacon.
A Prothean VI appeared when I activated the beacon and we had a chat with it, but right before we could get an answer what the Catalyst is, it detected an indoctrinated presence. Kai Leng...
He let me know the Illusive Man wanted a word with me via hologram once more. This man is still trying to control the Reapers. I can't believe how far he's gone. He was supposed to be on humanity's side, that's what he claimed he stood for... I can't stomach this.
Our chat was over and his goon attacked us. We held up just fine, but with fire support from a gunship he brought down a part of the place, getting away with the Prothean VI while I struggled to keep myself alive. Liara helped me up and I couldn't believe I had lost.
Lost to this f*cking bastard. Lost the data. We will not be able to finish the Crucible... Damn it!
Back on the Normandy I was angry, angry at Cerberus, at the Illusive Man, at Kai Leng, at the Reapers, and at myself. I didn't even recognize myself, I lost control over myself. It was just too much bullsh*t at once. But alright. I'm good. I'm still p*ssed off, but I can not let it get to me that much.
After a brief chat with Anderson I had an argument with Joker. He actually told a joke about asari in this moment. What is wrong with you? When I told him there's a war going on he said he's well aware we're at war, as Reapers invaded the colony where his father and sister live some time ago. Sorry to hear it.
His excuse for the jokes was that he tried to relieve me of stress. I learned Anderson actually told Joker to take care of me, but after telling him I'll be just fine I went to check up on the rest of the team. No need to babysit me. I've dealt with worse stuff.
Garrus had heard from his family, they made it off Palaven. At least one piece of good news, I'm glad for him.
On the other hand, he had to advice Victus to order a full retreat from Palaven. I supported this, then he asked me how I actually managed to get the salarians along. I didn't expect this now of all times, and something was telling me he had a suspicion, but I didn't give anything away. I was vague about it.
I went down to Javik just in time to see Liara trying to attack him. I stepped in, no fighting on this ship!
Liara threw a lot of accusations towards Javik, but he handled the situation surprisingly... nice. He found the right words to make Liara smile before she left. I thanked Javik, I didn't expect him to be so kind. It was a sweet gesture. But when he said Liara doesn't help us if she's grieving too much, I wondered if he really meant what he said. He said he did.
James tried his best to comfort me, letting me know once more he experienced something similar, but I'm not sure this helps. It's just frustrating. And sad. For both of us.
Oh well, I knew I had to overcome my own issues with what went down with Kai Leng rather soon, and I returned to the crew quarters, overhearing Tali talk to Garrus that Liara doesn't answer her comm, so I told her I'll be going in and talk to her.
I started to comfort Liara, but she was absorbed in her grief. I felt for her, but...
I sat down on her bed.
I remembered what James had said on the shuttle ride to Thessia. That Liara needs to block out the dead. He was right about that. And right now I need her to put this whole Thessia mess aside, I need to get her stop thinking about this and keep her occupied with what lies ahead, keep her mind off things.
So I asked her if she's gonna be ready for the next mission. It may sound harsh, but it worked. I could pull her out of her grieving state. She understood, told me she's actually glad to be able to focus on something else. Good.
I returned to the CIC to plot the course for our next destination. Traynor had tracked Leng's shuttle to Horizon earlier. What the hell is he doing there...?
Well, we will find out soon enough.
I think it's so great you can tell Garrus you sabotaged the cure, I'm thinking of going this route when I romance him at some point.
